This issue has been debated almost ad nauseam but, rather than wait for any BA seat sales, for J and F, if you’ve the inclination, there is always the European dogleg ruse which often comes up with better prices than the seat sales anyway. They’re available all year.

Thanks AD, the trouble is you cant offload avios to upgrade via eu routes, can you? Club in seat sale and upgrade to first is my mission. There is usually one starting around the same time as the Boxing Day DFS sale, but just wondered if a BA contributor knew of one appearing before then?
